IPC: G11B7/24062
Filed: 1993-03-10
Abstract: PURPOSE:To eliminate the interference at the time of reading information by forming first pit strings alternately of peaks and valleys in a specific direction and forming second pit strings in a specific relation with the first strings. CONSTITUTION:Tracks 2 for servo are alternately formed of the peaks and valleys on a substrate 1 and addresses 3 written with the address information of the tracks 2 and sectors are formed of the pit strings in the tracks 2. The substrate 1 has the addresses 3 in both of the peaks and valleys of the tracks 2. The states of the addresses A provided at the peaks and the addresses B provided in the valleys are shown in Fig. C. The directions of the beginning and end of the information of the pit strings are the same as for both A and B. The addresses 3 provided at the peaks and the addresses 3 provided in the valleys arranged by shifting these addresses in a circumferential direction. The end of a condensed light spot comes into contiguity with the addresses 3 and the interference of light arises and it is not impossible to read out exactly the information when this spot falls onto the addresses in case the addresses of the peak and valley tracks are aligned in the circumferential direction. Correct reading out of the addresses is then not possible. The interference is thus eliminated at the time of reading the address information.

Title: Semiconductor integrated circuit containing oscillator
Inventor: KUKIZAWA YASUNORI
IPC: H03K5/08
Filed: 1989-02-28
Abstract: PURPOSE:To suppress the generation of a through-current in an oscillation start period and to prevent the generation of a noise in a power source line by setting an input threshold of an oscillation output buffer circuit to a level being lower than a center voltage of an oscillation output in the vicinity of an oscillation start point. CONSTITUTION:When an oscillating circuit 1 starts an oscillation, in an oscillation start period, since amplitude of an oscillation output L of the circuit 1 is below input dead zone width of a Schmitt trigger circuit 16a of an oscillation output buffer circuit 2, a voltage of an output M of the circuit 2 is fixed to one level of a level in the vicinity of a ground voltage GND or a level in the vicinity of a power supply voltage VDD. As a result, in an inverter 17 for inputting the oscillation output M, it is fixed to the voltage VDD level or the voltage GND level as shown in the figure, therefore, no through-current flows to the inverter 17. Accordingly, it does not occur that an electric noise caused by a through-current as before is generated, and an abnormal oscillation of the circuit 1 is not generated either.

Title: Manufacture of semiconductor device
Inventor: MURAKAMI NORIO
IPC: H01L21/265
Filed: 1983-03-25
Abstract: PURPOSE:To prevent impurities from diffusion from a high impurity density substrate into an epitaxial layer by a method wherein an SiO2 film or a CVD film is formed on the surface of the high impurity density substrate and the epitaxial layer is formed after above film is formed. CONSTITUTION:An SiO2 film or an SiN4 film 2 is formed on a high impurity density P type Si substrate 1. The film 2 in a junction domain A, which forms an active element domain on the surface of the substrate 1, is selectively left. A low impurity density epitaxial layer 3 is formed on the whole surface. At that time, the layer 3 on the remaining film 2 becomes a polycrystalline epitaxial layer 4 and the layer 3 on the substrate 1 becomes a single crystal Si layer. Then a laser beam 5 is applied to turn the layer 4 on the film 2 into a single crystal layer 6. A thermal-oxidized SiO2 film or a CVD film 7 is formed on the layer 3 and an aperture is formed selectively above the film 2 only. Ions 8 of the different type from the impurities in the layer 3 are implanted. A deep diffusion layer 9 is formed by annealing the ion-implanted layer. At the same time, the impurities diffuse from the substrate 1 into the layer 3 to the depth of B but do not diffuse into the layer 3 on the film 2.

Title: Reactive power compensator
Inventor: SAKANAKA YOSHINORI
IPC: H02J3/16
Filed: 1992-03-06
Abstract: PURPOSE:To suppress voltage fluctuation of a power system on the primary of a transformer by compensating for the reactive power corresponding to a voltage reference in the direction of deviation when secondary voltage of the transformer deviates from a predetermined range. CONSTITUTION:When secondary voltage V3 of a transformer deviates a predetermined range upward, a reactive compensation power determined by the upper reference level V3U of the voltage V3 is selected as an intermediate value. Reactive power on the phase lag side, as compared with a case when a reactive compensation power determined by the primary voltage of the transformer is fed, is then fed in order to suppress increase of the secondary voltage V3 of the transformer. On the contrary, when the voltage V3 deviates downward, a reactive compensation power determined by the lower limit reference value V3L of the voltage V3 is selected as an intermediate value in order to suppress decrease of the secondary voltage V3 of the transformer. According to the constitution, voltage fluctuation of power system can be suppressed on the primary of transformer while preventing overvoltage or undervoltage.

Abstract: PURPOSE: To obtain flow rate signals of high accuracy with a simple constitution by detecting the electromotive force induced by fluid noise contained in the fluid being measured through electrodes constituting a space filter and selecting the specific frequency components of the AC components to provide the flow rate signals.  
     CONSTITUTION: With the opposing direction of the pairing electrodes 31, 32... provided to a pipeline 1 being set in the x direction, a plurality of these electrodes are disposed in the z direction at an equal spacing d. A signal adder 7 adds only the AC components occuring in the fluid noise from these electrodes 31... Since the pairing electrodes 31... are disposed in the z direction at the equal spacing d, the addition of the electromotive forces provide the signal f 0 ' obtained through a space filter, which may be obtained as the signal having been selected of only the frequency components corresponding to N.v/d(v: velocity of flow, N: 0,1,2...). The signal f 0 ' is removed of non-signal components by a tracking band pass filter 8 and is outputted as the signal f 0  (frequency f 01 ) through a waveform forming circuit 9. The filter 8 is able to maintain the function of a band pass filter at all times despite fluctuations in the velocity of flow because its central frequency f 01  is let to follow up the signal e 0  corresponding to the signal f 0 .

Abstract: PURPOSE:To prevent measuring errors attributable to electrical noise and improve the accuracy of transmitted beta-rays measurement by such an arrangement wherein the level of electrical noise of a detector and the initial stage of an amplifier is detected and their output is compensated accordingly. CONSTITUTION:Beta rays radiated from a source of beta-ray 3 transmit through a deposit layer 2 and attenuate in response to the thickness of the layer. A detector 4 is biased by a source of DC power and when beta-rays are illuminated, its output signal is sent to an amplifier 6 and a pulse height discriminator 7 and noises lower than a specified level are cut off. This specified level is set by such that noise components in the output of the amplifier 6 are detected by a noise level detector 8 and this output is sent to the pulse height discriminator 7. Thus, noise level is constantly detected and the discrimination level is controlled based on the noise level, therefore, the resolution of the meter is improved by one digit.
